[Laryngeal dyspnea caused by cervical hydatidosis: apropos of a case].

Hydatid cysts rarely present as a cervical tumor. We report a case of hydatid cyst of the neck in a child with multiple hydatid cysts in the liver, which was revealed by laryngeal dyspnea. Symptoms occurred in a six year-old country dweller, who presented with progressive laryngeal dyspnea. The chest radiographs showed extrinsic tracheal compression. A cervical ultrasonography showed a liquid filled mass evocative of hydatid cyst type 1. Explorative cervicotomy confirmed the diagnosis. The treatment was conservative after destruction of the parasite using a hypertonic saline solution. The immediate result was the disappearance of the laryngeal dyspnea.
